详细说明了用于化学分析和物理特性测定的代表性样品的实际要求。适用于产品在运输、装卸、连续流动和储存过程中。将在通用方法可用时进行修订。通过手动或机械去除恒定质量增量，在不减小颗粒尺寸的情况下进行取样。在密闭容器中储存增量并在环境温度下运输。在实验室检查之前，应保持与取样时相同的物理和化学状态。 也得到了IUPAC的批准。

Details the practical requirements for taking representative samples intended for chemical analysis and determination of the physical characteristics. Applicable to products during transport, loading/unloading, contimuous flow and storage. Will be revised when general methods are available. Taking samples is carried out without reduction of particle size by manual or mechanical removal of increments of constant mass. Storage of the increments and transport at ambient temperature in closed containers. Shall remain in the same physical and chemical state in which the sample has been drawn until the time of laboratory examination. Has also been approved by the IUPAC.
